Show DATA Oil POTATO GROWING (Continued from last week) ! w art Disease j The wart disease, appears first as ' little warts or wrinkles in the eyes oX 1 the young potato, and then as these ! grow together, a brown, spongy scab ; is formed which finally rots and bt , comes black. In general appearance, ' excepting color, ti.is spongy scab resembles re-sembles pieces of cauliflower. This disease causes the decay and destruction of the crop, and if the soil once becomes impregnated with the spores of this disease, it will de entirely en-tirely unlit for the growing of potatoes lor. Several years thereafter. The earth can hold and carry the disease j just as the potato plants. This is a disease until recently not known in the United States, and has not appeared at all in Utah so far as we have heard. But in Canada its ravages are becoming very severe, and the slightest sign of its appearance among your potatoes should cause you to attack the situation at once. If you will report the case to us we will instruct you how to go about, .the stamping out of the disease. I Scab Scab is one of the most common potato diseases, and all who uie or grow potatoes are familiar with the irregular,, sore-like blotches which sometimes are so n imerous as to cover nearly the whole potato. It may only affect the surface or it may penetrate pene-trate and break down the tissues almost al-most to the center. Unlike the wart disease which is ; very hard to combat, scab can be held j in check very easily. Clean, disinfect- ed seed planted in clean ground will produce a crop that is free of the disease. dis-ease. But if the fungu once gets into the soil it will live over the winter and infect the next "crop more severely than the preceeding one. If that happens, hap-pens, the field should be planted in j some other crop and kept free of pota-j pota-j toes for probably four or five years., sin-ie it does not attack other crops, this can be done. When you pick' your seed, select potatoes that appear to be freest from scab, but remember that the absence i of the characteristic surface marking i:: not eorv.'lusive evidence chat the po- tatoes are free from the fungus. They may have been in contact with scabby potatoes in the bin and consequently infected with scab spores. The only safe or businesslike thing to do is to disinfect your seed. Then you know you are safe. If scabbed potatoes are ! used for seed without having been sterilized, the resulting crop will almost al-most certainly be diseased, and in addition ad-dition the fungus will pass into ihe soil, where it is capable of living for several years and where it will infect plantings even of perfectly healthy seed. Disinfection Take fifteen gsllons of water and i put a half pint of formalin into it. I S .;ak your seed potatoes in this solution for two hturs. Dry vour potatoes and then plant. Be careful to see that after taking the potatoes from the solution so-lution you do not put them back into the old boxes or sacks. If you do that, they will be infected again and you will have your work to do over. If you wish to use the same containers again, you must disinfect them like you do the potatoes. Formalin is not expensive and can be purchased in almost any drug store. If you cannot get it at home, send seventy cents to us, and we will have a half pint sent from Salt Lake City. N. B. Peelings from infected pota- j toes, unless thev have been boiled, should not be given to pigs. Burning ! is the safest, and, in the end, probably j the most economical method of dealing with them. j |
